Carbon Microrod Material Derived From Human Hair and Its Electrochemical Supercapacitor Application

Here, Turkish human hair fibers were used as a carbon source at the synthesis of hair-sourced activated carbons (HHC). During HHCs sodium carbonate (Na2CO3) was added to process for an elevated activation by calcination different temperatures. Then obtained utilized modification paste electrode evaluate supercapacitance performance this HHC. Electrochemical investigation HHC modified electrodes have been carried out employing differential pulse voltammetry (DPV), cyclic (CV) and electrochemical impedance spectroscopy (EIS) measurements. The pore surface properties chemical structure investigated scanning electron microscopy (SEM), Brunauer-Emmett Teller (BET) analysis Raman spectroscopy. displayed Type-IV isotherm, which indicates existence micro-mesoporous on surface. Carbonization waste performed improve facilities three temperatures (200-250-300 °C). sample named HHC-250 (HHC calcinated 250°C) exhibited best charge storage capacity when electrode, among other with 26.88 F g−1 specific capacitance value (in 6 M KOH scan rate 100 mV s−1). Also, very attainable stability achieved from after 1000 cycles. presented system energy density 3.73W h kg−1. This work can serve guideline optimizing like biomass-derived matching their detailed investigations.
